The yield is nearly a theo retical' one. The same result can beoh taiued by saturating the aqueous solution of one part of the abovementioned oxyummouium ClllOlld in 5' to 6 parts of Watch withhydrochloric acid at a temperature of about 0 0.; the solution is heatedfor 24; to 48 hours to from 120-130 C. and eftei being cooled u dorkresinous substance is filtered oil? and the filtrate evaporated. on theremains as a viscous hrownsyrup which.

when heated with concentrated alkali lye or with pulverized causticpotash 01 with calcium or barium-hydroxid is decomposed intohydrochloric acid, trimethylsmin and erythreue, which letter isseparated and as alcove mentioned.

Theerythrene thus obtained is led through dilute sulfuric acid, dried overcalcium chlorid and condensed by coolin The yield is nearly theoretical.

We claim 1. The process of producing an erythrene hydrocarbon from ahalogen ammonium halogenid of a parafiin hydrocarbon containing at leastfour carbon atoms which comprises heating such halogenid with an alkali.

2. The process of producing erythrene from a halogen ammonium halogenidcon-- taining the nucleus graphically represented CH -EIH-CH -CHF whichcomprises heating such halogenid with an alkali.

hydrocarbon from a halogen 3. The process of producing an cryihrencammonium helogenid containing the nucleus graphicully representedc-c-o-c:c.

4. The process of producing r rythrene from the halogen ammoniumhalogenid of the following graphically represented formule:
